Get the Most of of Pumping with the Correct Breast Shield Flange Size

 

Every mom wants to get the most out of the time she spending pumping!  One of the best ways to make sure your pump is effective is to ensure your breast shield flange size is optimal.  An optimal fit engages the milk sinuses by compressing the areola the right way without causing nipple pain.

The infographic above shows you what to look for when you are pumping.  Most pumps including the best-selling Spectra breast pumps, include a standard flange size which is often 24mm.  Many moms find that is too large and opt for the 20mm breast flange.  And there are a few who need a larger 28mm or 32mm flange size.  But there are moms who until now had to look for another option if they needed smaller than a 20mm size.  Spectra has finally come out with a Spectra 16mm breast shield just for those moms!

In addition to using the right size flange, making sure your pump is functioning at the optimal suction level is so important.  Use your pump at the highest suction where you feel comfortable. Don't use a suction level that is uncomfortable or it will actually lessen your output because you are not relaxed.  

Opposite of having your suction at too high a level, low suction can cause less milk output as well.  This can often happen when a mother is not changing the breast pump valves and backflow protectors regularly.  These two components greatly affect your breast pump suction and therefore can greatly affect your milk supply.

So here is to comfortable, optimal pumping!

Troubleshooting your Spectra Breast Pump: Spectra Flange Size

How do you know when you need a different breast flange size?

Spectra breast pumps include the most commonly fitted flange size, 24mm breastshields. Although this is the most common size, many women will fit better in other sizes. A properly sized breast shield aka breast flange is important to ensure the best performance of your pump and the most milk output. An improperly fitted breast shield can hinder milk supply and cause discomfort. To determine the shield size you need, pump for five minutes using the standard size provided with your breast pump. Your nipple will expand while milk is being expressed, therefore it is important to measure after five minutes of pumping so that the size you select will provide adequate room. After five minutes, measure the diameter of the nipples at the base with a tape measure that uses millimeters. Click the link to access a printable tape measure.

Ideally, you should select a shield size that is 2-3mm larger than this measurement, but up to 5mm may be acceptable.
Spectra flanges are available in the following sizes:
Spectra 20mm Breast Shield - Small
Spectra 24mm Breast Shield - Medium
Spectra 28mm Breast Shield - Large
Spectra 32mm Breast Shield - X-Large

See the images below for fitting examples.

Ensuring the proper fitment is essential for protecting milk supply especially in moms who use their pump frequently for working or exclusive pumping.  An ideal fit compresses the milk sinuses properly ensuring good milk transfer, less pain and fewer clogged milk ducts.

When purchasing new breast shields, you should also replace your duckbill valves.  Duckbill valves and breast shields that are not sterilized together may not fit well causing the duckbill valves to be loose on the breast shield.   Normally, Spectra valves should be replaced every 6 weeks for moms pumping 15 times per week.  Backflow protectors do not need to be replaced as often but at minimum, Spectra Backflow Protectors should be replaced every 2-3 months.  

Best wishes for comfortable, effective pumping!
